"Some warmer air is also lurking for later next week after the near miss from Lorenzo's remnants".
Karen is slowly strengthening and nearing tropical storm strength with maximum sustained wind speeds of 35 miles per hour and stronger gusts.
Karen's center was approaching Puerto Rico and was expected to pass near or over land on Tuesday afternoon before moving into the western Atlantic Ocean, the U.S. National Hurricane Center said in a midday forecast update.
Heavy rain and tropical storm-force winds are expected, CNN meteorologist Michael Guy said.
Three tropical systems are now churning out in the Atlantic basin.

Tropical storm Karen is moving northwest near 7 miles per hour with maximum sustained winds at 40 miles per hour with higher gusts.
The quake struck just as Puerto Rico's residents are preparing for a tropical storm, which is expected to pass near or over the island Tuesday, bringing 2 to 4 inches of rain with up to 8 inches in isolated areas.
It's heading "generally westward" over the Atlantic at about 16 miles per hour.
Lorenzo is now located around 270 miles southwest of the southernmost Cape Verde islands off the coast of Northwest Africa with maximum sustained wind speeds of 50 miles per hour.
This is the latest five-day forecast track of Tropical Storm Lorenzo, one of three tropical storms now active in the Atlantic hurricane basin. It is forecast to reach the island Tuesday with life-threatening waves that could last for several days.
The forecast track of Lorenzo appears to curve back out to sea, and not present any threats to land.
